LUBRICATOR.

Application nled August 1G, 1923. Serial No. 657,812.

This invention relates to a lubricator for internal combustion engines, the general object` of the invention being to provide means for atomizing the oil and mixing it with air and then introducing the mixture into the cylinders of the engine.

This invention also consists in certain other features of construction and in the 4combination and arrangement of the several parts7 to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing the invention in use.

Figure 2 is an enlarged elevation of the device itself. p

Figure 3 is a longitudinal sectional view through the device.

Figure 4c is a section on line 4--4 of Figure 3.

Figure 5 is a section on line 5-5 of Figure 3.

Figure v6 is a detail perspective of a supporting member.

Figure 7 is a transverse section of connecting means included upon the upper portion of the device.

In these views 1 indicates a cylinder which is in communication with an oil container 2 by means of a tube 3 which is supplied with the sight openings f1. The How of oil from the chamber 2 is controlled by the needle valve 5 and a float operated valve tl also controls the supply ot oil into the cylinder l. The float is shown at T and its stem at 8. Thus when the level oit oil in the cylinder 'l reaches a certain point the valve 6 will be seated to close the oil passage from the container 2 but as soon as the level drops the valve will open again and permit more oil to iiow into the cylinder. rIhus the level of oil in the cylinder 1 will remain constantowing to the automatic valve control means. The cylinder 1 is provided with an air inlet 9 and an outlet 10 which is connected by the tube 11 with the inlet manifold A of the engine. Valve chambers 12 are formed in the cylinder. these chambers being in communication with the interior ofthe cylinder through the ports 13 and one chamber is in communication with the inlet 9 and the other with the outlet 10. Each chamber contains a ball valve 14 for controlling the inlet ports thereof.4

From the above it will be seen that the suction created by the moving pistons of the engine will draw air through the cylinder and this air will pick up oil as the same is dropping into the cylinder from the container so that a mixture of oil and air is introduced into the cylindersof the engine.

When desired drops of water may be caused to fall upon the screen 15 which covers the air inlet 9 so that the mixture will be moistened. This water can be carried in a tank 16. i

This device will make a great saving in oil and I lind that it eliminates carbon and increases the efficiency of the engine. Itis:` especially designed for the two cycle type of engine.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

that I claim is y A lubricating device comprising a cylinder provided with an air inlet port on one side and a discharge port on the other side, ball valves for the ports, an oil container carried by and communicating with the cylinder and adapted to deliver oil in the path of the air passing from said air inlet port to said dis` charge port, a float for the cylinder. a stem carried by the float, and a float operated valve carried by the stem adapted to control the discharge of oil from the container to maintain a constant oil level within the cylinder.

In testimony whereof I aflix my signature.
